Laco Ulm 39 Special Models 39 mm Hand-Wound

The Laco Ulm 39 Special Models is a high-end pilot’s watch that combines the classic Flieger Type A design with a finely finished hand-wound mechanical movement, reflecting Laco’s historic heritage and German watchmaking excellence.
This model stands out for its functional elegance and refined execution, designed for discerning enthusiasts who appreciate both traditional navigation watch aesthetics and high-quality mechanical finishing.
Inside, it features a hand-wound Laco 261 movement, based on the Sellita SW 261 in elaboré grade, and equipped with a stop-seconds function. The movement is beautifully finished with Côtes de Genève bridges, thermally blued screws, sunray-finished ratchet and crown wheels, and a ratchet wheel engraved with the Laco logo, all visible through the sapphire case back.
The case is crafted from stainless steel with polished and sandblasted finishes, combining elegance with an instrumental character. It is fitted with an anti-reflective sapphire crystal and a screw-down case back with a large sapphire display window, offering an unobstructed view of the movement.
The matte black dial follows the original navigator watch execution with a Type A layout, featuring Arabic numerals and indexes filled with Super-LumiNova C3, as well as a small seconds subdial at 6 o’clock, ensuring clear and balanced readability.
All hands are thermally blued and filled with Super-LumiNova C3, providing excellent visibility in low-light conditions and an elegant contrast against the dial.
The watch is completed with a brown leather strap fitted with a stainless steel buckle, offering comfort and enhancing its classic and refined appearance.
With its 39 mm diameter and especially slim profile, the Laco Ulm 39 Special Models offers perfectly balanced proportions and outstanding wearing comfort, making it an ideal choice for everyday use and for collectors of high-quality Flieger watches.
